Very clever how you cut the inlet hole in the cylinder!

This is by far the best cyclone I've seen built. very well done. Thanks for sharing

Hi. I have never seen so well done dust collector. Amazing. Congratulations.

Wow - loads of massively clever ideas there, especially your template @ 6:46 That is awesome.

7:08 so satisfying to watch... An excellent video with amazing results! Nice work!

Great job! would like to see the inside of your shop vac and the filter after a more strenuous test. Thanks for the upload!

Nicely done Sir. Your efficiency test was brilliant.

probably one of the best dust collector video. i built mine very easily after seeing your video. Thanks a lot.

Fantastic workmanship and design!

Excellent video with cool and fitting background music. My greatest compliments to a ingenering gifted young man. Thank you for sharing your skills. Now I found the right cyclone dust collector/ Antonio,Thailand.

Good point. I see the difference and appreciate you punting it out. Seems like a more efficient design as you demonstrated.

Great build. I like the way you made the inlet very smart.

Oh Man. Thank you for making a great instructional video about your cyclone project. You are helping mankind to grow and prosper.

Excellent workmanship! I think that I have found the answer to my 1st stage dust collection, only on a larger scale.

Thanks for sharing the awesome build!

Great build and explanations! Thanks for sharing!

Wonderful, very clever design. Thanks for video

Love the clear top, its like staring into a camp fire.

Very nicely done.

the fits are so satisfying, amazing job !

Really nice. I like that. That will fit my needs perfectly and all the parts are really easy to get.

Very useful, as i'm contemplating something similar, but probably scaled up some. One of these next to each machine would allow a central vacuum to be connected, but with the debris collected local to the machine, instead of being transported back to a central location.

Fantastic!Your skills are outstanding.

Based on your video, I built the same device. Works great. I am very happy with it. I do not remember when I had to change the bag in the vacuum cleaner. Thanks !

Thanks for your video, I have made one based on your design using some large mains water pipe and it works great. I have tested mine and it is about 99.8% efficience which I am really pleased with.

I was totally on board with this project until you busted out the pantorouter, then I was like "oh hell no" and then a link pops up "click here for a more common method" and I was right back on board again and was like "oh hells yes". Great work, this is the best cyclone vid out there.

More more compliments!!! Special work!!! 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

very good job ! Nice séparator. Salutations from France.

This is impressive. I have been working on a Thien baffle extractor today, just a rough one, my first. I have an idea which I think might make these extractors more efficient in terms of suction loss. It'll be a bit more difficult to build but I'll have a go and make a video

Well done and a fun little project.

Thanks again for your help. Well done.

It looks really good, very well done.

For the efficiency, just put the once filtered saw shavings through the seperator a second time, weigh before and after the second run through. Great work btw, excellent standard all round.

Nice work! To improve even further on the efficiency of the cyclone, could you increase the difference in height between the inlet-pipe and the notch in the outlet-pipe? You have built more of these obviously, what have you learned to improve your design even more?

Very nice😃 good job mister Cosmas B. 👍👍

Outstanding!

Also proves you have a really clean shop! :-0) Great job

very well done. I appreciate you method for the efficiency testing. Have seen a bunch that claim 99% efficient but there methods were usually just guesses.

beautiful work

I take it that you like festool colours,great video,great design

Dammit I peed a little when the inlet fits the bucket! great job

C'est vraiment très ingénieux. Du très beau travail.

I llike it, nice and smart done. thx for sharing/

really good video will save me fortunes on bags for the fein extractor

Congrats! Great job

That was probably the best one I've seen yet. I just wish there was a way to do this inside of the vacuum cleaner itself; so much wasted space inside a normal machine, and it is still the fine dust that eventually clogs the filter. I'm a little hesitant to start building one of these, because I'm afraid to get "sucked in" by the process- I could see spending a lot of time on one of these. Anyhow, awesome work.

Very nice build! Do you share plans / measurements? also, which type of double sided tape did you use? Thanks!

Great Build!Any chance on an Update Video/Comment on a Large Scale Clean-Up. Would love to see the Efficiency Percentage.

A very neat job indeed, great work, hope mine will be half as good,...I doubt it. Thnx

Wow. That is cool the way you put the baffle on the end of the pipe. Mine is ever so ugly, compared to this. I do however have as close to 100% as I can measure, just like yours. I am of he belief that the top needs to be pure cylindrical, and not a bucket (slightly conical).

Piu' bello di quelli che si comprano in negozio.. Complimenti... 👏👏👏

Great job!

Nice tablesaw/router table, did you make that? Nice work.

You are really a genius

nice colors

Can you list the glues you use? Can you tell us what glues to use with different material? Seems you use a lot of the same stuff :) Great build, really, smooth and firm!

Thanks for sharing 👍

Hey Cosma, Nice built again! I have build also a cyclone utilizing your videos. However my baffle keeps collapsing very easy. Any ideas how to avoid this? -Chris

Great Work!! Very inspiring!! The black hose has an inner diameter of 32 mm (1 /14 inch)? Seems like you improvise a reduction after the 90 degrees curve, is that right?

Cosmas, I'm in the process of making a separator very similar to your design, which I like very much. Would you be kind enough to answer a couple of questions for me? 1) How close to the top should the intake pipe be? 2) I'm using a 9-inch diameter tube that looks to be similar to your orange pipe and would like to know if the length of this tube matters. In other words, is there any advantage to making the distance to the baffle closer or farther away from the intake? Thanks so much from Arizona.

hey awesome project I have 3 question for you, the green disc sitting in the end off the suction pipe inside the cyclone, what is the diameter of that disk....? And the length of the gray pipe with the green disc in the end, how long is that form the inner side of the plexiglass too green disc....? and the length of the notch made in the gray pipe how long is that....?

Is the hat vac the best you have built ? It seems that downward force is good in keeping the dust down

If Carlsberg made cyclones they could not beat that, brilliant Sehr Schone, Having that thickness of plexi is great Ill have to have a go, very instructive video I congratulate you

Шикардос! Очень грамотный подход.

Nice engineering sir.

Awesome wood shop....

Very good thanks.

Que bien, cuantas herramientas tienes para mostrar.

Absolutely Brilliant Cosmas! you are a superb perfectionist to which I one can aspire too. Having good quality and precise equipment really can do wonders eh? especially that router pantograph jig you made. And as always, a great presentation video. Good choice of music too. A big like from me. Cheers Cosmas :)

Super boulot merci.

Hi. I want to build this but I also have a problem withthe fine dust filtering since I only have a regulare house vacuum, cleaner. do you have any recommendations as to how to go about this matter? perhaps a reccomendation as to what air filter to buy on line and how to install i (maybe as a separate station between the cyclone and the vacuum) Thnx

Thanks . I will try.

Parabéns pelo vídeo é show de bola.

Excelente desde Cali Colombia Saluditos

Great !!!!

Im impressed! Good joob

Spitze! Sauber gemacht! Aber Deine Werkzeugausstattung ist auch sehr professionell.

Awesome!

Perfect cut ;)

How many inner diameter - lower circle (which is attached to a gray tube), and the distance from it to the Plexiglas? Thanking you in advance.

Beautifull

Witam. Jaki jest wymiar wewnętrznego dysku? Może mi pan powiedzieć również, jaka głęboka jest długość rury centralnej, pod pleksi i ile jest również długość części pociętego na centralnej rurze? Dzięki za odpowiedź. Pozdrawiam z Polski

What is the efficiency when it's half or 2/3 full?

Hi +Cosmas B - great build! It really shows that you have a lot of experience with these cyclones after building so many ... I'm thinking of building one too, and this really seems to be a very good design - compact, efficient and easy to build. I was wondering if you have experimented with how far down in the cyclone the best position for the baffle is? It just looks like it's not flush with the bottom (which I would have expected). And just for a size comparison: is that a 60 liter bucket?

Thanks for sharing the video, no wonder Germans are so ahead in technology!

Deadly accurate! What I most of all appreciate. I have one question about dust. This system good catches sawdust but I suffer of fine dust. Especially of MDF. How about that? How much fine dust pass through and left on vacuum cleaner filters?

very clever and super Quality Job maintain all the way, What if your Orange Tube is 3 " Longer ,,Is that make Any Different ?

Cosmas, congrats for this excellent design. I'm going to replace the cyclone part of my self designed shop vacum and I'm intending to use your design. Could you please tell me what is the diameter of the large PVC tube you have used? Best regards.

Sehr schön.

1:44 That's Cosmas B on lead router!

Interesting that you left the baffle opening as a complete circle. Most people have a partial opening of just 240-270 degrees.

What is the light brown pipe? I thought it might be sewer pipe but could not find any that size at my local builders merchant. Great job and build by the way

Don't think you need the extra length pip into the drum (WITH SIDE CUT OUT).. just 0.5 to 1in portending into. Nice work nice Tools too.

Great!

Great job, are you selling your design now?

For camera, get a head band to hold it so you can use both hands :)

can I use my router to cut plexyglass? or required special bits?

Good day, very good work! Do you also produce a separator for sale? I would be interested. Please communicate the price. Thank you.

Alter a few years of use, don’t you think that the green disk held by the knotched pipe inside the cyclon should be lowered ? Thanks Sergio

Nice work. How many have you already made?
